Mounting the Generator
Refer to Figure 5-1 for dimensions used to properly mount the Apex generator.
Connecting Cooling Water
This generator is water cooled. Do not operate it until water is connected and the
cooling requirements are met. For information on cooling requirements, see “Cooling
Specifications” on page 3-10.
Apex water fittings vary depending on the option installed on the generator. Water
fittings are identified by the option in PIN position 16 (for information about using the
PIN to identify and find information about your generator, see “Using this Manual to
Find Information for Your Generator” on page 1-1).
To Connect Cooling Water:
1. Connect the input and output water connections and tighten securely.
2. Turn on the water and ensure that there are no leaks.
3. Be sure that the flow rate, pressure, and temperature are within the minimum
specifications required to operate the generator (see “Cooling Specifications” on
page 3-10).
Installing the Optional Water Control
The water control connector is a 2-pin, miniature, power jack, Switchcraft p/n L712A.
Table 5-1 and Figure 5-2 provide the connector pin locations and descriptions for the
water control connector on the generator. The signals on this connector may be used
with an externally mounted water control solenoid to inhibit the flow of water to the
If you connect the cooling water on multiple units in series, be sure that
input water temperature to all units is less than the maximum input water
temperature.
Do not use de-ionized water for cooling purposes. De-ionized water
causes both corrosion and erosion of cooling manifolds.
